To me it looks like the 5DIII image is slightly overexposed...or perhaps the 1dsII is a bit underexposed. Something is not right there and until you can get the washed out exposure corrected you cant make a good comparison on detail.

Hi. Don't know how scientific your tests were. But as a 1Ds Mkii owner myself, I've yet to be convinved that newer cameras offer significantly improved image quality at ISO 100 (where I'm at for most of the time). The 5Diii might have better dynamic range, but I don't know how noticeable this would be in the real world. And of course, if you try to shoot at higher than ISO 3200....

I haven't been on here in a while, and honestly I went to the "other" brand. But I'm still a big fan of Canon.

Anyway, I'll say that for one, your test is not very scientific. I would use more lenses and scenarios to compare. If you compare a 5d classic RAW file to a 5d3 RAW at base ISO, it's likely the resolving power will be negligible at best. The major innovations in sensor technology happened years ago -- CMOS sensor.

What we see now are different algorithms in processing, as well as some *slight* changes in sensor design that allow for lower temperatures and other variables to achieve less noise. We're splitting hairs these days. What you do get in newer DSLRs are faster FPS, better ISO performance, better weather sealing, better LCD screens, etc. Don't expect too much -- except large drops in value as the newest model is released. Which is the reason I dumped my 5d2. the Mark 3 had nearly the same IQ, according to reviews. I didn't need FPS, AF points, etc. as a landscape guy.

I'll even go on the record as saying my D800 does not significantly out-resolve my former 5d2. The shadows are much cleaner, however, and RAW files are probably better...uhh....programmed? Outta my league there!! But the 14-24 (I don't own one) and 16-35VR (I do own one) are the reasons I switched from the 5d2 and 17-40L (which I used to own). And all of the newer, highly economical F/1.8 primes they have released.

You have used the correct word - "slightly".

There is a small difference in exposure due to slightly changing daylight between the two shots.

I tried to compensate, but the difference was less than 1/3 stop, so this was the best I could do.

Do you think that the difference in exposure of less than 1/3 stop, can make one camera having lower detail resolving power than the other and will it introduce moire instead of real detail?

Off-topic here, how do you find the 16-35mm in the corners?.. I've been considering it for my D800 as the 17-35/2.8 is not up to my desires for landscapin.' The 17-40L was not very good until stopped WAY down and even then it depended on focus distance.As for 5d2 vs d800, I sold the former, bought 2 of the latter.

ON topic, I'm not surprised the old 1D series produces a slightly more pleasing image than the 5D3 but there should be some reasons for that. 5D3 should be producing slightly better raw files..

Then again, I sold all my newer Canon bodies and kept the old ones because they deliver nicer looking images. And then added bodies from the competition because they provide even better raw files.

Here are two 100% crops... Scroll them to the right to see those windows with white blinds:real usable detail in 16.7mp 1Ds MkII files,mushy moire in 22mp 5D MkIII files.

If you down-res the the 5DIII photo to match the 16.7mp of the 1DsII, it will look sharper. Or enlarge the 1DsII image to match the 22mp of the 5DIII and it will look less sharp. The 5DIII is presenting a bigger image of the same scene, so it looks less sharp. If you had a 36mp photo of the same scene and viewed it at 100%, it would look even less sharp. Also the unfortunate moire effect in the 5DIII photo is usually a result of greater resolution, not less.

Both look extremely good — very, very similar. If I had to choose, the 5DIII photo looks slightly more natural to me. Extra sharpness in 100% crops can look overly digital and is not necessarily welcome.

The thing I noticed between the my 1dsII and the 5DII & III is, the 1DsII has less DR and in a sense makes the photo seem crisper since the image is natively more contrasty.

Oh yes, that's a good point. The camera with greater dynamic range will present a less contrasty image. The camera with less dynamic range will present an image that looks crisper overall. But greater dynamic range is usually preferred as you can always add contrast.

This really makes no sense.

If I have tiny real details and texture in the white blinds on the windows in 1DsII sampleand I only have moire in the 5DIII sample,

why do you think that just by downsampling the 5DIII file to 1DsII file size, the detail that is not present in the 5DIII file will magically appear,...or that just by upsampling the 1DsII file to 5DIII file size, the visible detail in the 1DsII file will magically disappear?

The resolved details are present in the files or they are not.

You can just try what you have suggested - use the crops that i have posted above, resize them both way to match each other and see if the lost details will appear in 5DIII file when you downsize it, or if the fine resolved details will dissapear from 1Ds file by upsizing it.

Illusion of perceived sharpness achieved by stronger microcontrast is not the same as detail resolving ability.

1DsII files have both - more visible resolved detail and higher microcontrast.

Remember that RAW files from both cameras were developed with the EXACT same settings,so you can not say that file from one camera was sharpened more.

I'm a professional photographer for 20 years.I have been shooting with 1Ds MkII since the day it was introducedand I know every bit of its possibilities very well.

After all this years I wanted to upgrade to a more modern body.I was hoping for a high MP body but we got 1Dx and 5DIII.

I (naively?) decided to try the 5DIII since it has more resolution and the 1Dx is not good investment for my needs (studio) if the big MP camera is around the corner.

The moment I started using the 5DIII in the studio (100 ASA, etc), I realised that I don't really like its RAW files compared to my old 1DsII files.

When I opened first 5DIII RAW file in Capture One (confirmed later in DPP and Adobe CR),I thought for a couple of seconds that I must have missed the focus a little bit.

But I did not.

I was just used to the crispness and details in 1DsII files that are just not there in 5DIII files.

I was disappointed since I wanted badly to like the 5DIII and to keep it for use in the studio.
